Abstract: A motion state monitoring system, a training support system, a motion state monitoring method, and a program capable of suitably managing measurement results according to an attaching direction of a sensor are provided. A motion state monitoring system according to the present disclosure monitors a motion state of a target part of a subject's body. The motion state monitoring system includes an acquisition unit, an attaching direction detection unit, and a control processing unit. The acquisition unit acquires sensing information of a sensor attached to the target part. The attaching direction detection unit detects an attaching direction of the sensor. The control processing unit outputs information related to the sensing information in association with the attaching direction.

Abstract: An input device with a plurality of terminals for inputting information in a touch panel includes three direction detecting contacts that are projecting portions to touch three positions on the touch panel and form a triangle having vertexes on the three positions, and at least one information identifying contact that touches the touch panel together with the three direction detecting contacts so that specific information to be displayed on a display panel is identified according to a placement position of the information identifying contact with respect to the triangle.
